UDP is a core communication protocol of the Internet protocol suite used to send messages in packets without prior communication. It provides checksums for data integrity and port numbers for addressing different functions, but does not guarantee delivery, ordering, or duplicate protection. It is suitable for time-sensitive applications where error checking and correction are not necessary. It was designed by David P. Reed in 1980.
